Quick Verdict

The WORX WA0860 ACS accessory and the GARDENA SILENO Minimo serve completely different purposes. The WORX is an add-on collision avoidance system for existing Landroid robots, while the GARDENA is a complete robotic mower. If you already own a WORX Landroid and want smarter navigation, the WORX accessory is a cheap upgrade. If you need a full robotic mower from scratch, the GARDENA is the better choice despite its lower rating.

Where WORX Wins

Cost and value. At $299, the WORX ACS is roughly half the price of the GARDENA. For existing WORX Landroid owners, it’s a straightforward upgrade that adds obstacle detection—helping the mower avoid toys, hoses, or pets. The high rating (4.2) and large review count indicate strong user satisfaction.

Ease of installation. The ACS accessory clips onto compatible WORX Landroid models without tools. No wiring or programming is needed—just attach and enable the feature. This makes it ideal for users who already own a WORX mower and want to improve its navigation without buying a whole new machine.

No yard-size limit. Since it’s an accessory, the ACS works with any yard that your existing Landroid can handle. You’re not constrained by the mower’s range or battery life—those are already determined by your base unit.

Where Gardena Wins

Complete system. The GARDENA SILENO Minimo is a ready-to-go robotic mower with a boundary wire, charging station, and all necessary components. For new buyers, this eliminates the need to purchase a base mower first. It’s designed for small lawns up to 300 m²—perfect for urban gardens or tight spaces.

Silent operation. The “SILENO” name highlights its low noise output, typically around 58 dB. This matters in quiet neighborhoods or if you mow at night. The WORX ACS doesn’t affect noise, but the base mower you pair it with may be louder.

Brand ecosystem. GARDENA offers a broader range of robotic mowers, spare parts, and service centers. If you later need a larger mower, you can stay within the same brand. WORX’s ACS is a niche add-on, limiting future upgrade paths.

Which Should You Buy

Buy the WORX WA0860 ACS if: You already own a WORX Landroid robotic mower and want to improve its obstacle avoidance. It’s a cost-effective upgrade that boosts navigation intelligence without replacing your current machine. The high rating and low price make it a no-brainer for existing WORX users.

Buy the GARDENA 15202-41 SILENO Minimo if: You are purchasing your first robotic mower and have a small lawn (up to 300 m²). It’s a complete, quiet solution out of the box. Despite its lower rating, it offers a reliable entry into automated mowing, especially if you value brand support and low noise.
